* new: tacklelib: `YamlEnv` class supports hierarchical yaml configuration files to read variables with a compound nature to postpone an environment variable declaration to a moment of execution of an executable
* new: tacklelib: `tacklelib.sig.xsh` script to suppress signals to avoid accidental signal interruption in critical code segments
* new: tacklelib: `tacklelib.cache.xsh` script to wrap the `fcache` module to make workarounds over it (see details in the `README_EN.txt` file)
* new: cmdoplib: `yaml_load_config` function can load environment variables for a particular context (global/environment variables)
* new: cmdoplib: `yaml_expand_*` functions can expand for a different containers (str/list/dict/value) or use additional containers to search in for replacement values (at second in dictionary, at third in global variables)
* new: cmdoplib: support run `ssh-pageant` as a background process to enable access svn repositories through the svn+ssh protocol from the `git svn ...` command
* removed: tacklelib: `tkl_get_parent_imported_module_state` function is removed as not needed anymore because the search logic is based on the stack frames now
* changed: tacklelib: always export to all imported modules in the `tkl_declare_global` function
* changed: cmdoplib: `CONFIGURE_DIR`, `SCM_NAME` and `CMD_NAME` variables made global in all imported modules to be able to use them directly in command calls
* changed: cmdoplib: [continued] `git_push_from_svn` function
* refactor: tacklelib,cmdoplib: yaml functionality
* refactor: cmdoplib: git/svn functionality
